The space left between the two electrodes is filled with an electrolyte that ensures charge transportation through a redox couple, typically iodide/tri-iodide. Finally, the two electrodes are sealed together with an encapsulant for electrolyte confinement. For stability purpose and manufacturing facilitation, the solvents used at laboratory scale can advantageously be replaced by non-volatile compounds, or even a solid entirely.


Thanks to the redox couple present in the electrolyte, electrons can be transported from the cathode’s surface to recombine with the “holes” of the oxidized dye molecules, closing the regeneration loop. This light-induced cycle can then restart all over again, as the solar cell produces electricity. Oxygen evolution reaction is a crucial reaction for many energy technologies such as high efficiency water electrolyzers, or photo-driven water splitting, regenerative fuel cells, and advanced rechargeable metal-air batteries. Accordingly, high performance catalysts are urgently needed to speed up the OER, lower the high overpotential required to drive the reaction and reduce the energy consumption. So-called supercapacitors store electrostatic charge in the form of ions, rather than electrons, on the surfaces of materials with high specific areas (m2/g).

Since aluminium is quite an active metal, the traditional smelting technique used for iron did not work, and electrolysis, with the significant development of the electrical generator, was the only practical method to enable the electrolytic aluminium production.

An anode supported cell 55 cm2 in size with optimized microstructure was implemented in SOFC stack configuration and tested over 50 RedOx cycles. While the performance was nearly constant, the OCV decreased by only 0.1 %/cycle. The performance was three times lower compared to small cells, but shown to be due to poor electrical contact and limiting fuel flow and composition in the employed stack assembly. Electrical energy storage in ECs occurs due to the formation of electric double-layer on the electrodes’ surfaces and to some extent surface oxidation/reduction. The capacitance due to the former is called electric double-layer capacitance and that due to the latter is called pseudo-capacitante.

Furthermore, stacked sheets of graphene derived from exfoliated graphite provide a modular approach to exploring lithium storage in layered carbon as well as layered carbon/metal nanocomposite. Nitrogen is one of the most abundant elements in the atmosphere and most inert also. The electrochemical reduction of nitrogen is more difficult than the CRR due to presence of three covalent bond between nitrogen atoms, which have high bond energy of 941 kJ/mol and therefore difficult to perform. For the NRR suitable catalysts are required, and Earth Abundant Electrocatalysts are good candidates for this reduction. Tafel slope, b, is the inherent property of a catalyst, and is determined by the rate limiting step of HER; the b values quoted are for 25 °C and a symmetry coefficient of 0.5.

Landfill and use as fuel were more practical with a solid. In this project, we aim to develop an architectural materials based on carbon-coated TiO2. The design is started from core-shell hybrid nanospheres, which have TiO2 nanoclusters as incorporated core and polymer as both host matrix and shell. These obtained monodispersed nanospheres will form close-packed array either through gravitational sedimentation or centrifugation. Therefore, the whole array will become well conductive.
